REVERSE-SPINDLE DRIVING- MECI-IANISM FOR SPINNING FRAMES.

Application filed February 9, 1928. Serial No. 253,073.

My invention has reference to an improvement in spinning frames and more particu larly to an improvement in a reverse belt take up and spindle drive mechanism for the spindles of spinning machines or the like.

The object of my invention is to provide a spinning machine with a reverse belt take up and spindle driving mechanism for running spindles in either direction, whereby the idlers automatically take up the-slack of the tape without adjusting the idlers.

Another object of my invention is to construct such a reverse belt take up and spindle driving mechanism, whereby when one idler is carrying the power to drivethe spindles, the other idler is also carrying thepower by automatically taking up the slack of the tape and vice versa.

My invention consists in the peculiar and novel construction of an automatic reverse belt take up and spindle driving mechanism for spinning machines said reverse belt take up and spindle driving mechanism having details of construction, as will be more fully set forth hereinafter and claimed.

Figure 1 is a vertical transverse sectional view of a spinning machine provided with my improved reverse belt take up and spindle driving mechanism.

Figure 2 is a top plan view of Figure 1, with the greater portion of the spinning machine broken away, and

Figure 3 is an enlarged detail view of onehalf or one element of the automatic reverse belt take up and spindle driving mechanism, with one of the idlers.

In the drawing 4 indicates the frame of a spinning machine having the usual ring rails 5, 5, spindles 6, 6, with whirls 7, 7 and bobbins 8, 8, on the spindles 6, 6, which are rotatably supported in the usual way. A tape driving drum 9 extends lengthwise of the machine. This drum 9 is rotatably supported at each end on the frame 1 .and power driven in either direction in the usual Way.

My improved reverse belt take up and spindle driving mechanism consists of two reverse belt take up elements a and 7) constructed identically alike and placed in the machine in oppositely disposed reverse positions, as shown in Figure 1. Each reverse belt take up element consists of a bracket 10, adjustably secured to the upper part of the frame 4:, over the drum 9, and the inner end a longitudinal rod 11- ported on the rod 11 and has a downwardly extending bifurcated arm 14, with bearings 15, 15, for an idler 16. A stop arm 17 having a stop end 18 is adjustably secured to the rod 11, by a bolt 19, which contacts with the rod 11. This stop arm 17 lies between the forked end of the lever 12, and extends over the lever 12, in a position for the lever to engage with the stop end 18.

The operation of my improved reverse belt take up driving mechanism is as follows. The endless tape 20, when running in the direction of the full line arrow 0, goes upwards from the drum 9 and over the idler 16, of the driving element a, then outwards around two whirls 7, 7 on spindles 6, 6, then across to opposite side and around two whirls 7, 7, on spindles 6, 6, then back around the idler 16, of the element 6, and then to the drum 9, as shown in Figures 1 and 2. With the tape driving in this direction the idler 16, in the element 6, is forced away from the opposite idler, thereby bringing the lever 12, up against the stop end 18, of the stop arm 17. The lever 12, in the element a, now moves downward and the idler 16, in the element a now moves towards the idler 16, in the element 6, thereby taking up the slack of the tape. With the drum 9 running in the direction of the dotted arrow (Z, these operations are automatically reversed.

It is evident that the placing of the elements of my improved reverse belt take up driving mechanism could be changed so that both driving elements a and Z2 may be supported on one rod 11 and other details of construction could be varied and achieve the same results.

Having thus described my invention I claim as new 1. In a spinning machine having a frame, a driven drum and rotatably supported spindles, a reverse belt tensioning driving mechanism comprising two oppositely disposed.

levers, means for adjustably securing the stop arms and an endless bolt operatively connecting the drum, the idlers and the spindles.

.2. In a spinning-machine having a frame, a driven drum rotatably supported on the frame, oppositely disposed spindles rotatably supported on the frame, stop arms operatively supported in the frame, oppositely disposed idler arms each idler arm having an idler and a lever in a position to engage the stop arm, driving means operatively connecting the drum, the idlers and the spindles, means for operatively supporting the idler arms, means for operatively supporting the stop arms and means for adjusting the stop arms.

3. In a spinning machine having a frame, a driven drum rotatably supported on the frame, oppositely disposed spindles rotatably supported on the frame, stop arms operatively supported in the frame, oppositely disposed idler arms each idler arm having an idler and a lever in a position to engage the stop arm, an endless belt operatively connectmg the drum, the idlers and the spindles, means for operatively supporting the idler arms, means for operatively supporting the stop arms and means for adjusting -the stop arms. 7

4. In a spinning machine having a fame, a driven drum, and rotatably supported spindles, two slack belt take up mechanisms with idlers,an-endless belt operatively connecting the drum, the spindles and the idlers, each slack belt take up mechanism having a bracket, a rod fixed to the bracket, a stop arm adjustably secured to the rod, an idler pivotally secured to the rod and rotatably supporting the idler, said idler arm having a lever in a position to contact with the stop arm, means for securing the bracket to the frame of the machine and means for adjusting the stop arm on the rod, for the purpose as described.

In testimony whereof, I have signed my name to this specification HARE ION O. NELSON.
